15-5PH
Type 15-5PH stainless steel is one of the widely used precipitation-hardening stainless steel grades. With its refined composition and controlled microstructure, it offers excellent strength, toughness, and corrosion resistance after heat treatment. Grade 15-5PH is commonly applied in industrial, aerospace, and marine manufacturing fields, particularly where high mechanical performance and dimensional stability are required.
